"These leatherback turtles are our model workers in the Maldives and they work hard to help us clean up jellyfish in the waters around our Maldivian islands. “

The coach proudly explained to Xi Ming and Xia Ritian.

"Jellyfish are so beautiful and gentle, these turtles eat them...... It seems to be a cruel feeling, a sweet and kind heart in summer, and I feel very dislike for those big sea turtles. ”

People always sympathize with the weak, but sometimes the laws of nature tell us that it is not like that.

Seeing that everyone didn't like turtles, so at this time, a coach said with a vibrating walkie-talkie under the water, "Hehe, that's because you don't know the benefits of jellyfish, although jellyfish are beautiful and docile, but they are actually very fierce, under the umbrella of those jellyfish, those slender tentacles are their digestive organs, but also their weapons, the tentacles are covered with stinging cells, like poisonous wire, can shoot venom, after the prey is stinged, it will quickly paralyze and die." ”

"Ah, that's terrifying. ”

Xia Ritian was obviously taken aback by the coach's explanation.

"Yes, the tentacles of the jellyfish hold these prey tightly, retract them, and suck them up with the polyps underneath the umbrella, each of which is able to secrete enzymes that quickly break down the proteins inside the prey. Because jellyfish have no respiratory and circulatory systems, only primitive digestive organs, the captured food is immediately digested and absorbed in the coelenter. ”

"Jellyfish mostly live in stagnant waters, they are extremely tenacious, they hardly need oxygen, so you will find them in the deep sea area of several thousand meters. The appearance of jellyfish is not a phenomenon of environmental improvement, but a symptom of environmental deterioration. With the severity of water pollution, abundant nutrients, and a large number of catastrophic plankton appeared, resulting in a large number of fish deaths, but jellyfish began to flourish, but this is the prelude to another disaster, jellyfish eat everything, plankton, fish eggs, small fish, big fish ~ none of them miss the net, its prosperity makes it difficult for fish to regenerate, and the consequences will be irreversible!"

"The jellyfish's body is shaped like a transparent umbrella, and the diameter of the umbrella body can be large or small. The umbrella body of the common jellyfish is not very large, only 20~30 cm long, while the umbrella body of the large jellyfish can reach 2 meters in diameter. From the edge of the umbrella grows some whisker-like bands, which are called tentacles, and some tentacles can be as long as 20 meters ~ 30 meters, which is equivalent to the length of a large whale.

"On the seaside, in the hot summer, when someone swims in the tide on the beach, sometimes he suddenly feels a tingling pain in the front of the chest, back or limbs of the body, as if he has been whipped by a leather whip, and it must be another jellyfish stinging people. However, if you are stung by a jellyfish, you will only feel burning pain and redness, as long as you apply anti-inflammatory drugs or vinegar, it will reduce the swelling and relieve the pain in a few days. However, some jellyfish, such as killer jellyfish, sea bee jellyfish, they secrete very poisonous, if they are stung, there will be difficulty breathing within a few minutes, at this time you need to implement artificial respiration, or inject cardiac agents, otherwise you have to hang, which is why we recommend that you wear a wetsuit to prevent being stung by poisonous jellyfish ......"

"Jellyfish are really that dangerous. ”

"Yes, it's very dangerous, jellyfish are definitely more dangerous than you think, most jellyfish once they encounter prey, they never let go easily, and the powerful and deadly jellyfish if this is like this to humans, then humans are also quite dangerous, but no matter how powerful the jellyfish are in our Maldives, they also have natural enemies, that is, the leatherback turtles we just saw, they can freely shuttle in the group of jellyfish, easily tear off their tentacles with their mouths, so that they can only roll up and down, and finally lose their ability to resist, and become a turtle's meal" Good meal".

Because there is a special substance in the stomach juice of the turtle that dissolves the poison of jellyfish, it can eat jellyfish. ”

……

All the time.

We in the Maldives have its natural enemy, leatherback turtles, which freely shuttle through the jellyfish colony, easily tearing off their tentacles with their beaks, causing them to roll up and down, and finally lose their ability to resist, becoming a "good meal" for the turtles. And in the stomach juice of the turtle, there is a special substance that can dissolve the poison of jellyfish, so it can eat jellyfish.

That's why leatherback turtles are our protectors and model workers!

The seemingly gentle creatures of the ocean are the most dangerous creatures, and the seemingly domineering and untouchable giants are the guardians of humanity...... Nature's has taught us a magical lesson.

The group of giant turtles first created some tension for everyone, and then the jellyfish made people wary again.

When the giant turtle is completely gone.

Followed by.

Other colorful fish in this area of water also appeared in front of everyone.

Feel those colorful fish swimming freely around you, and the blue and clear water is dotted with light, making everything look so beautiful and dreamy.

Xi Ming's heart couldn't help but erupt in literature and art.

Blue sky

ocean

This generous embrace

Gently put your arms around me

Constantly light, constantly thin

The fish are flying

Colorful and coquettish

The corals swayed

Purple and red

I'm drunk

In this swaying blue romance.

Some people say that the moment you dive into the water, you know why you love the sea, in the sea water you can experience a kind of freedom, stretch, body and mind as if penetrated by the sun's rays, unrestrained, unhesitating, into nature.

At this time, the underwater instructor, that is, Xi Ming, specially arranged, specializes in catching summer sweets in the water and swimming fish and enjoying the beautiful photos of the coral scenery.

"Look, these corals are not plants, they're animals, and the main body of these reefs is made up of polyps. The polyp is a coelenterate in the ocean, which feeds on the small plankton in the ocean, and can absorb calcium and carbon dioxide from the seawater as it grows, and then secrete limestone, which becomes its own shell. ”

"Each individual polyp is the size of a grain of rice, and they live in groups of people, metabolizing, growing and reproducing from generation to generation, while secreting limestone and bonding together. These limestones are then compacted and petrified to form islands and reefs, also known as coral reefs. Due to the attachment of polyps, many coral reefs often have large numbers of coral polyps attached to their bottoms. ”

Xi Ming felt that this inland boy was a long insight this time, and he had risen his posture, he used to think that coral was a plant, but he didn't expect coral to be an animal.

Well, I have short hair......"

At this time, the sun was shining, snorkeling in the seawater, and Xi Ming followed the guidance of the instructor to watch the colorful and beautiful polyps hunting.

There are many small holes in the middle of the reef, and from those small holes, there are constantly reef fish swimming in and out, and there are many types of reef fish, such as colorful long and short, round, and triangular.
